With over 140 years of history, O&K Antriebstechnik is a centre of engineering excellence, recognized worldwide for high quality products for applications in the mining, construction and marine & offshore industries.
Acquired by Bonfiglioli Group in 2016, this leading brand develops, manufactures and offers a full range of final drives such as slew drives, travel drives, winch drives and cutter drives.
The origins of the company date back to the founders, Benno Orenstein and Arthur Koppel, who at the end of the 19th century began – in the middle of the Ruhr – to develop railway systems for foundries and mines. Gradually, O&K became the benchmark for heavy-duty machines and the best-known brand in the world for the design and manufacture of excavators and mining shovels.
Today, O&K is recognized for its solid expertise, its capacity to adapt the design of its products depending on customers’ requirements and the high technological standards of development.
The FR Series is the best solution when designing large wheeled off-road machinery. With a compact design, high torque and load capacities, a negative multi-disk parking brake and an optional disengagement device to tow the vehicle in an emergency, these solutions precisely match the application requirements.
The FP Series are perfectly suitable with any crawler, large excavators and milling machines. Thanks to compact, rugged design, high torque and load capabilities these solutions are the best possible option for the machine. All units are available with a fail-safe parking brake and for most cartridge type fixed or variable systems. Different disengagement systems are available on demand for all the sizes.

The Bonfiglioli S series provides the safest and most effective solution for cranes, excavators and forestry machines. Its compact design allows it to perfectly fit cranes, excavators and special equipment where installation space is limited.
The planetary winch gearboxes of the FW Series are suitable for a large spectrum of winch applications thanks to the availability of a wide torque range. The compact design allows the gearbox to be integrated into the winch drum. The failsafe brake can be integrated inside the gearbox or mounted externally, with common lubrication for the gears. Electrically driven versions are available with both in-line and right-angle configurations. Torque ratings are organized by FEM class, in accordance with minimum approved class safety factors for gears.
Dual stage planetary drive units with integrated pulley support, designed for cold planers, milling machines and surface mining machines with engine power from 80 to 1200kW and different rotor widths. The offset input option ensures higher machine productivity due to the increased cutting depth. The shiftable 2 speed solution allows two possible cutting speeds with huge benefits in terms of machine performance.
The specific design of the O&K Jack-up Series has been assessed by ABS to work in lifting and lowering legs and hulls of drilling and service jack up rigs, lift boats and windmill installation vessels. Units can be in-line or have a drop box for offsetting the motor installation. They can be electrically or hydraulically driven, with or without a negative parking brake. These jack-up drives can deliver integrated pinions from m50 to m100 and lantern pieces with integrated torque arm for easy installation. Units have class approval from ABS and DNV GL, and full 3.2 certification of the load-bearing parts of the gear transmission with full traceability from raw material to final machined component.
